Andrea Michelle Reyes was 23 months old when she was reported missing in 1999 in New Haven, Conn. But thanks partially to new DNA technology, the now 27-year-old has been found after her mom Rosa Tenorio allegedly took her and fled the country, according to authorities.

In a March 5 statement, the New Haven Police Department said investigators located Andrea in Puebla, a city in central Mexico. They were able to do so after a Special Victim’s Unit with a focus on missing persons re-opened her cold case in 2023.With the help of interviews, search warrants and social media, a detective determined that Andrea, whose mother never had custody of her and who was in the care of her dad when she went missing, “had been taken by Rosa to Mexico and was residing in Puebla, a city of over a million people,” per police.
